ANSWER
Answered 2022-Jan-26 at 16:45The problem is that the R binary in rocker/r-ver:latest
is compiled against a different BLAS library to the one which the numpy on PyPI is compiled against.
This was explained to me by Tomasz Kalinowski here.
The solution is to ensure numpy uses the same BLAS libraries as rocker/r-ver
's R binary does. An easy way to ensure this is to compile numpy from source. This compilation could be performed at either image build-time or container runtime.
To compile numpy at container runtime we can leave our Dockerfile
as is, and add a call to system2()
after our initial call to reticulate::virtualenv_create()
. Altering test.R
to become:

QUESTION
I am trying to sort the neighborhoods by their populations. I used heap sorting algorithm in C#. I created an Array which keeps the population of the neighborhoods named "arr". And created an array which keeps the name of the hoods . It works good but how can I get output of sorting with name of the neighborhoods?
...ANSWER
Answered 2022-Jan-10 at 18:45From an OOP perspective you would keep the two properties (name and population of a neighborhood) together in one object. Then when you sort the objects, you'll still have the associated data right there.
There are several ways to do this. For instance, you could create tuples.
Here is how that is applied to your code:
QUESTION
Not sure what I am doing wrong, but when copying a PSCustomObject in Powershell to an array element, this is copied by reference. See this:
...ANSWER
Answered 2021-Dec-30 at 22:23.psobject.Copy()
performs shallow (member-wise) cloning of [pscustomobject]
instances.
Since your simpleMediaItem
property contains a reference to a .NET reference type (which happens to be another [pscustomobject]
instance), it is the reference that is copied, so that both the original [pscustomobject]
and the clone obtained via .psobject.Copy()
reference the very same object.
For deep (recursive) cloning (for which there is no universal solution), you'd have to create a custom implementation.
You can avoid the problem altogether using a custom class

I'm trying to run an Rscript through entrypoint but for some reason when I do this it fails to recognize the file. Here is an example.
...ANSWER
Answered 2021-Dec-23 at 01:16The --entrypoint
argument takes the name of the executable, like bash
, Rscript
, python
, etc. The arguments to that executable would go after the docker image name.
QUESTION
I found vignette on using the AzureAuth package with Shiny which seems to be a modified version of this httr Sketch of shiny + oauth.
It's unclear, to me at least, how to connect the names in that guide to what I can find in my Azure Portal.
That guide asks for tenant, app, resource, and redirect.
I presume that for tenant and app I should use the IDs from here:
For resource, do I leave in the c("https://management.azure.com/.default", "openid")
or do I change it to the endpoints found in the portal, ie. https://login.microsoftonline.com//oauth2/v2.0/authorize?
I changed it to just "openid"
.
Should the redirect
variable be the URL of my app, the callback URL or something else?
ie. https://myapp.azurewebsites.net or https://myapp.azurewebsites.net/.auth/login/aad/callback
I'm going with the former. This is all in a docker container using rocker as the base.
With all this I'm getting 500 errors after I authenticate. Of course, Azure has middleware inbetween my container and the exposed internet that is redirecting to their login regardless of anything in my code. The problem is in the handoff from being authenticated to the callback. That's where things seem to break.
Edit: Turns out I was barking up the wrong tree entirely. The problem I was having was this...
Query/headers too large on Azure if auth enabled

Answered 2021-Nov-25 at 09:41Should the redirect variable be the URL of my app, the callback URL or something else? ie. https://myapp.azurewebsites.net or https://myapp.azurewebsites.net/.auth/login/aad/callback
Firstly, change the redirect URI in your app registration in the portal as follow:
https://myapp.azurewebsites.net/.auth/login/aad/callback
Now, change the redirect variable in your app code as follow:

I am going to try and explain this the best way I can, but I expect that I will have to reword a few times.
So what I have is a list of diagrams that have certain specs. I have built a table with the various diagrams and their specs in Excel. I have built a GUI using PySimpleGui for the users to interact with. There are drop down boxes with the specs in them that they will use as inputs for the code to use to search for these diagrams. Here is the code for the GUI

QUESTION
For a daily report Rmarkdown script that I would like to encapsulate in a docker container I face a problem with a plotly plot that is created from ggplot facet_grid and then transformed using ggplotly.
When I run the script locally on R studio my plot is working as intended:
When I run the script through my docker container, it is completely greyed out:
The data is actually there, it is just not showing:
There is no differences between the scripts except for where I run it and I actually do not know where to look for solving that bug.
Here is the ggplot+plotly part inside the rmarkdown chunk:

Answered 2021-Oct-13 at 07:59I solved it by changing my image and installing plotly with the install.packages function, not with the binaries:
QUESTION
I have a rails application that combines some R code. It works fine, and now is the time to dockerize it. I tried creating the docker based on a ruby image, which failed installing R properly, and then the other way around (R image, installing ruby using rbenv
as explained here) which failed too.
Has anyone experienced with this combo?
EDIT: I have managed to create a docker using the R image, however this requires a tiring installation of many ruby dependencies. So consider this side done.
Still, why won't the other way (installing R on ruby image) work?

Answered 2021-Sep-14 at 08:42You can use the stand alone version of ruby-build.

Install rocker
You can use rocker like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
